Earlier I noticed problem with usb connection (see previous posts) but today the camera died. When I turn the camera on, it makes a sound, the blue led is on but the screen is not turning on. Then the camera hangs and one has to remove the battery to turn it off. The same happens when it is connected to power supply with or without the battery. With battery the red light is on. I have observed the same reaction two days ago. But after several attempts the camera started working normally. Today it won't. Any ideas what could be wrong? I cannot run it in bootloader mode as the camera is not detected in pc (https://sjcam.com/community/threads/sj8-pro-usb-connection-stopped-working.18275/).
